Title: Method for transmitting/receiving signal in a communication system
Inventor: CHO MIN HEE
IPC: H04B7/26
Filed: 2006-03-06
Abstract: A method for transmitting and receiving signals in a communication system is provided to prevent deterioration in the receiving performance of an MS(Mobile Station) by making a BS(Base Station) transmit/receive DL signals in consideration of ICI(Inter-Cell Interference). A BS creates a preamble signal(811), and executes data scheduling in consideration of the channel state of each MS and priority according to a preset scheduling method(813). Based on the scheduling result, the BS creates DL bursts(815), and then allocates the created DL bursts on the basis of a frequency domain correspondingly to an applied MCS(Modulation and Coding Scheme) level(817). The BS creates a MAP message in accordance with the allocated DL bursts(819). Then, the BS creates an FCH(Frame Control Header) according to the MAP message(821), creates the preamble signal, the FCH, the MAP messages, and the DL bursts into a DL frame in accordance with a DL burst frame structure(823), and transmits the created DL frame signal to MSs(825).
